On December 11, 1919, the citizens of Enterprise, Alabama erected a monument to the boll weevil, the pest that devastated their fields but forced residents to end their dependence on cotton and to pursue mixed farming and manufacturing. A beetle measuring an average length of six millimeters, the insect entered the United States via Mexico in the 1890s and reached southeastern Alabama in 1915. It remains the most destructive cotton pest in North America.
